I have had this thing for 14 years on a 7 Rem mag. It has held zero the whole time. The glass is not all that great and no target knobs. I have only had two problems--once it slid in the rings and I could not figure out what went wrong, groups opend up. ( not the scopes fault) Two years ago before hunting season the power ring became VERY difficult to turn. Problem seemed to have gone away.
They have a no questions ask return policy.
They are not top of the line and would expect them to be equivlant to low end nikon and bushnell. Begin cheap and dependable i would give it a thumbs up...Scope has been replaced with a 6.5X20X40 leupold.
